Irony of ironies: The Trap fell into a trap of its own making: Curtis has mistaken a perversion of negative liberty for the thing itself.
His suggestion that a twisted Cold War definition of negative liberty became the flip-side of what it despised (utopian positive liberty) was very convincing. But negative liberty is not the narrow, selfish ideology of Cold War paranoia: it is simply the belief that liberty exists in the space outside the state, as opposed to the belief that liberty can only be found within it. (Or, even more simply, negative liberty bans actions and positive liberty demands them.) Negative liberty does not exclude a positive ideology or demand we ignore the complex web of relations and desires in society: as Curtis pointed out, if it doesn't acknowledge those things, it implodes. All it says is that people can create those things best outside formal structures: it is more democratic, in a real sense, than idealistic fantasies that rest on a utopian government to become reality. (And so are doomed to failure.)
The Trap fell apart at the end by portraying Tony Blair as an apostle of negative liberty, when in reality he's the exact opposite: a believer that freedom is to be found in a vast, benevolent state, exempt from restrictions because of its special goodness. Mr Blair's attempt to harness a narrow definition of the free market as the means to his utopian ends is the "third way" -- but this bout of ideological adultery doesn't hide his true roots. The civil liberties Blair has destroyed are the embodiment of negative liberty, and he removed them because he believes the state must impose virtue. His narrow idea of "perfect people" might, or might not, have its roots in a fanatical perversion of negative liberty, but his ultimate end, and the means by which he's imposing it, belong with Rousseau.
Negative liberty does not demand that anyone outside its narrow definition of "normal" be removed by extraordinary measures: it demands that, unless one person's freedom removes freedom from another, they be left in peace. It says governments are not qualified to impose goodness. On this specific issue Curtis has distorted reality to make it fit his grand theory. So, thanks for another superb series, but remember, no one is immune from the trap …
